David Dale was the third son of Robert Owen, a Welsh reformer who moved to the United States and established a social experiment at New Harmony, Indiana, where David Dale also lived.
He conducted the first geological surveys of Indiana, Kentucky, and Arkansas. His first geological work was as an assistant mapping the geology of Tennessee, in 1836. He was appointed the first geologist for the State of Indiana (1837–39), and worked as the State Geologist of Kentucky in 1854–57.
He was appointed State Geologist of Arkansas in 1857, continuing as the Kentucky geologist without pay. He returned to Indiana as state geologist in 1859–60. Owen died November 13, 1860, at the age of 53.
While in Arkansas, Owen drew the first known picture of a natural rock formation in Natural Steps, Arkansas.
